Factor the following expression using the GCF: 2dr – 4r.

2r(d-2)

Step-by-step explanation:

1. 2 and r are both factors of the monomials 2dr and -4

2. Put it as 2r and divide each monomial and put it into parentheses.

3. 2dr/2r is "d" while -4r/2r is -2 since the r cancels out

3. After your done dividing each term b your GCF multiply your GCF to whatever is in the parentheses. 2r: GCF  (d-2): Factors

2r(d-2)

9/2 In mixed fraction its 4 1/2

please tell me if i got it wrong!
